KENNEDY SPACE CENTER, FLA. - As the sun begins to rise in the early-morning sky after its departure from Launch Pad 39A, the Space Shuttle Atlantis slowly travels on the crawlerway toward the Vehicle Assembly Building. This marks the second rollback for Atlantis since July because of hurricane threats. Atlantis, which is targeted fo liftoff later this month on the STS-79 Shuttle mission, is returning to the VAB because of the threat from Hurricane Fran. The threat of Hurricane Bertha forced the rollback of Atlantis in July. Atlantis currently is scheduled for launch on the fourth Shuttle-Mir docking mission around mid-September.
